Simultaneous removal of ofloxacin & rhodamine b dye from wastewater by activated jamun seed powder

Abstract

Through the processes of carbonization and chemical activation, a low-cost adsorbent was created in this work using bio waste jamun seed (Syzygium cumini) that was previously available. It was used to extract Rhodamine B, a color dye, and the prescription medication ofloxacin from their aqueous solutions. Using "Field Emission Scanning Electron Microscope" (FESEM), "Fourier Transform Infrared Spectroscopy" (FTIR), and particle size analysis, the surface morphology and surface area of the repaired activated Jamun seed dust were examined. It was discovered that the surface area of activated jamun seed (ACJS) was 366.39m2/g. Following CHNS analysis, the powdered jamun seed had a carbon content of 55.68%. After three hours, 90-99 % of the ofloxacin in the aqueous solution was eliminated while maintaining the mixture's pH at 5. Additionally, activated jamun seed powder (ACJS) removed 50% of the Rhodamine B from the aqueous solution in 3 hours while keeping the pH of the solution at 5. This was accomplished with activated jamun seed powder (ACJS). ACJS's maximum adsorption capacity was 39.97 mg/g. With R2 = 0.99158 and 0.99732, the adsorption kinetics were in accordance with a linear pseudo 2nd order model. The Langmuir linear isotherm fitted with experimental data was demonstrated by the isotherm investigation. Thermodynamics research shows that adsorption is a viable, exothermic process. The powdered jamun seed is the source of activated carbon, which is also inexpensive and may be used for up to many cycles without lowering the effectiveness of OFC and Rhodamine B removal.
